STUDY OF TERNARY LIQUID LIQUID EQUILIBRIA AND OF MULTIPHASE EQUILIBRIA

In this study, we have calculated LLE and LLVE in ternary systems, using the PT equation of state with the mixing rules of Kurihara et al. Only two interaction parameters per binary system are used to correlate VLE and LLE data simultaneously and the results appear to be comparable with the activity coefficient approach using the same number of adjustable parameters. A wide range of systems has been studied. The multiphase P-T diagram for the system H2S-CO2-CH4 is also plotted and compared with the experimental data.
